Active Degassing of Deeply Sourced Fluids in Central Europe: New Evidences From a Geochemical Study in Serbia

“…Serbia also exhibits high regional heat flow (up to 130 mW/m 2 ) and geothermal energy potential (Doljak & Glavonjić, 2016;Horwarth et al, 2015). Previous work in the central-western Balkan Peninsula has found several natural gas manifestations and gas-rich thermal waters (e.g., Burić et al, 2016;Rosca et al, 2016;Todorović et al, 2016). However, the source of these gases, and the geological/tectonic controls on their migration through the crust, remain uncharacterized.…”

Electrical Resistivity Imaging of the Northeast Carpathian Volcanic Arc With 3‐D Magnetotellurics Reveals Shallow Hydrothermal System

“…Hydrogeological investigations conducted in the northern Pannonian Basin west of our study area (close to the Hungarian border) have revealed that the geothermal aquifers are located at a depth of 800-2,400 m, with an identified geothermal gradient of 45 55°C km 1 and temperatures exceeding 140°C estimated at depths beyond 3,000 m (Rosca et al, 2016). Based on its chemical composition, thermal springs in the study area were classified as hydro-carbonated mineral waters related to post-volcanic phenomena, within the area of volcanic mofette haloes, the waters are carbonated, carbonated-chlorinated and chlorinated, rich in calcium, magnesium, and sodium, with mineralization generally up to 5 g l 1 (Rosca et al, 2016). More detailed quantitative information on the chemical composition of the springs is not available to us.…”

Miocene tectonic activity at the boundary between NE Pannonian and NW Transylvanian basins (Romania): Insight from new seismic data

“…At the contact between the northeastern Pannonian Basin (NE‐PB) and the northwestern Transylvanian Basin (NW‐TB) sits the Baia Mare region (black square in Figure 1), not only well known for its mineral resources but also for its geothermal potential demonstrated by high heat flow values and the presence of hot springs (e.g. Demetrescu, 1982; Roşca et al, 2016).…”

“…At the contact between the northeastern Pannonian Basin (NE-PB) and the northwestern Transylvanian Basin (NW-TB) sits the Baia Mare region (black square in Figure 1), not only well known for its mineral resources but also for its geothermal potential demonstrated by high heat flow values and the presence of hot springs (e.g. Demetrescu, 1982;Roşca et al, 2016).To date, geological and tectonic knowledge about this region has been documented by sparse geophysical data only (vintage seismic reflection and well data) and surface geology collected at the margins of the Baia Mare junction region (e.g. Ciulavu et al, 2002;…”
